Description
A classic example of 20th-century luxury horology, featuring the famous 'Constellation' observatory case back. This ladies' timepiece combines jewelry-like elegance with precision engineering. The mesh strap provides a fluid, fabric-like drape on the wrist.
Key Features
Observatory Case Back with 8 stars (symbolizing chronometer records), Milanese mesh strap, and the 'C-shape' or rounded case evolution.
Color & Finish
Yellow gold finish with visible significant oxidation and patina. Case back shows a circular brushed finish with the iconic 'Observatory' logo.
Hallmarks & Stamps
Observatory logo on case back representing the Geneva Observatory; eight stars above the dome. Possible reference numbers near case edges (blurred).
Dimensions Estimate
Case diameter: 23mm-25mm; Bracelet width: 12mm; Petite/Ladies' standard fit.
Gemstones & Inlays
None visible on case back; dial may contain indices or diamond markers typical of the Constellation line.
Clasp & Closure
Sliding fold-over clasp system common to Milanese mesh bracelets allows for adjustable sizing.
Chain & Links
Milanese Mesh (stamped or knit-style) construction. Flexible metal wire weave with rectangular end caps connecting to the lugs.
Craftsmanship Details
Precision Swiss assembly. The mesh is machine-knit for uniformity. The case back engraving is stamped with high-relief detail, though currently obscured by wear.
Authentication Indicators
Alignment of the Observatory logo; star patterns; quality of the mesh weave. Red flag: Blurred stamps and excessive base-metal show-through suggest high wear or lower-tier plating.
Origin & Maker
Switzerland; Omega SA. The Constellation is Omega's flagship luxury chronometer line.
Era & Period
Late Vintage / Retro (circa 1970s-mid-1980s). Indicated by the integrated mesh band and case profile.
Age Estimate
Circa 1975-1985 based on the specific bezel lug design and mesh bracelet integration.
Cultural Significance
The Constellation was a status symbol of mid-century success, representing the pinnacle of Swiss accuracy and high-society style.
Condition Notes
Fair. Significant 'brassing' (plating wear) where the base metal is visible on the lugs and bracelet links. Surface scratching and grime accumulation present.
Value Estimate
$150 - $450 USD. Value is based on the brand (Omega) and horological interest rather than metallic gold weight, given the plated nature.
Care & Maintenance
Gentle cleaning with a soft brush and slightly damp cloth only. Do not submerge as vintage seals are likely compromised. Avoid polishing cloths on plated areas as it will further remove the gold layer.
